I'm happily with Page Plus, and I now want a better/newer phone. Primarily, I want a bigger screen and longer-lasting battery.. which seem to come on 4G phones... which I discovered means the phone has to be flashed. I'm generally good with computers and technology, but I know very little about flashing (yet), apart from what a few articles have explained. What I'm wondering, first off, is this: 1) Does flashing affect the reliability of the phone? 2) Does it make the phone more prone to problems? 3) Do apps and everything work the same as a non-flashed phone? 4) Does a flashed phone require more technical skills to use/operate? ie: Would I find myself stuck, needing to do something but no idea how to do it? 5) I know it voids the manufacturer's warranty, but does anyone know if Square Trade cares? 6) Would the answers to questions 1-4 change depending on the phone? The three phones that I'm looking at right now are the HTC One, the Galaxy S3, and the Galaxy Note II.
